6,096 Products

Fluid Handling

Pressure-Regulating Valves

Pressure-Regulating Valves

Reduce inlet pressure to a lower outlet pressure to protect sensitive equipment

Pressure-Relief Valves

Pressure-Relief Valves

Protect equipment by opening at a set pressure and closing when the pressure drops; for repeated use

Airlocks

Vent gases out of flasks, carboys, and other containers without letting dust and oxygen in

On-Off Valves

Start and stop flow through a line

Flow-Adjustment Valves

Flow-Adjustment Valves

Gradually open and close to control the volume of air and liquids through a line

Check Valves

Permit flow in only one direction by closing when flow stops or reverses

Diverting Valves

Diverting Valves

Redirect flow between ports

Orifice Valves

Restrict the flow of liquids and gases to precisely control rate and pressure

Vacuum Breakers

Vacuum Breakers

When pressure drops, vents open to prevent suction from drawing liquid back upstream

Tap Valves

Pierce copper tubing for a secondary line to humidifiers and ice makers; also known as saddle valves

Drain Valves

Vent air or discharge liquids to remove excess fluid from your system

Float Valves

Open or close a pipe connection when liquids in a container reach a set level; also known as ballcocks

Backflow-Prevention Valves

Backflow-Prevention Valves

Dual checks stop flow from reversing and contaminating your system

Float Valve Bodies

Float Valve Bodies

Pair with floats and rods to create float valves that meet your needs

Mixing Valves

Blend hot and cold water, steam, or oil to maintain a set outlet temperature and prevent scalding

Hose and Hose Fittings

Hose and Hose Fittings

Flexible and stronger than tubing; often used to convey liquids and gases under pressure

Pipe and Pipe Fittings

Pipe and Pipe Fittings

Generally thicker and more rigid than tubing for distributing liquids and gases through your facility

Safety Equipment

Respirator Filter Monitors

Respirator Filter Monitors

Track the quality of incoming air as it travels from your air line to your respirator
